a manager wants to know whether or not the employees of his company are stressed due to work. he creates a poll and asks all the employees to voluntarily respond. what type of sampling bias is observed in this poll?\nself - selection\nnon - response\nundercoverage\npre - screening or advertising
Answer
# Brief Explanations:
Self - selection bias occurs when individuals choose whether or not to participate in a study. Here, employees voluntarily respond to the poll, meaning those with stronger opinions about work - related stress are more likely to respond. Non - response bias would be about those who don't respond at all, undercoverage is about parts of the population not being included in the sampling frame, and pre - screening or advertising is not relevant in this context.
# Answer:
Self - selection
